双宾动词的被动语态

双宾动词即指带双宾语的动词，它们在变为被动语态时，有以下两种情形值得注意：

(1) 有些双宾动词(如award, buy, give, leave, lend, offer, pay, show, teach, tell等)在变为被动语态时，既可把间接宾语(指人)变为被动语态的主语，而把直接宾语(指事物)保留下来(称为保留宾语)，也可把直接宾语(指事物)变为被动语态的主语，而把间接宾语改为介词to 或for引起的状语(到底用to还是for，与所搭配的动词有关)。比较：

He gave her some money. 他给她一些钱。

→ She was given some money. / Some money was given to him.

He bought her a watch. 他给她买了一快表。

→ A watch was bought for her. / She was bought a watch.

(2) 有些双宾动词(如bring, do, make, pass, sell, send, sing, write等)通常用直接宾语(指事物)作被动语态的主语，而将间接宾语用作保留宾语(其前根据情况用介词to或for)：

Father made me a doll. → A doll was made for me.

He wrote her a letter. → A letter was written to her.

(3) 有些双宾动词(如answer, deny, envy, refuse, save, spare等)通常用间接宾语(指人)作被动语态的主语，而将直接宾语用作保留宾语：

He answered me that question. → I was answered that question by him.
